The use of the cyclic redundancy check (CRC) algorithm for integrity check during firmware update makes Ubiquiti airFiber AF2X Radio firmware version 3.2.2 and earlier vulnerable to firmware modification attacks. An attacker can conduct a man-in-the-middle (MITM) attack to modify the new firmware image and bypass the checksum verification.
The product does not validate or incorrectly validates the integrity check values or “checksums” of a message. This may prevent it from detecting if the data has been modified or corrupted in transmission.
